Electronic Defenders® add an extra layer of protection against major break-in attempts to your security door lock compared to traditional mechanical models. The keyway is protected by a manganese plate that completely seals the slot and is only released with a numerical activation code to be entered on the built-in keypad.
The electronic Defender® also allows personal activation codes to be provided for friends, family and trusted persons, unlike magnetic models, where a duplicate of the special magnetic key must be provided to each person. Service codes can be deleted at any time using the master code.
